Yeah, you could do a little wrapper for this. I've got one that
checks hostname, and if you're try to run netscape on one of the
listed servers, tells you not to, recommends a specific host that
was set up for remote X apps, and exits.

You could check for $HOME/.netscape/lock, which should be a
(broken) symlink to IP:PID. You could also do some fiddling
with `ps | grep`. Be aware of the dns helper process.

ronin:~$ ps aww | grep [n]etscape
 3910 C0  I       0:00.02 (dns helper) (netscape)
27422 C0  S       0:09.14 /usr/local/netscape/netscape

If you want to get fancy, you could check both, and try to do some
automatic reaping of netscape processes without controlling terminals
(maybe with the x flag to ps).

For this, I'd say go with the ps method. You could generalize it
to however many X displays you've got. If $NS_COUNT >= N, then
say "too many netscapes". `grep -c` could be handy for this.

Although, in general, multiple netscapes run by the same user tend
to cause problems. I know they cause problems with mailchecking,
and I think they cause problems with things like saving bookmarks.
